How do climate-resilient health systems tie into One Health?

• A. They prepare for climate impacts by maintaining surveillance, resilient supply chains, and cross-sector collaboration.
• B. They focus only on clinical care in hospitals.
• C. They consider climate but ignore cross-sector coordination.
• D. They rely solely on technology improvements.

Answer: (A)

The idea being tested is that climate resilience in health systems is strengthened when it follows a One Health approach—linking human, animal, and environmental health through shared surveillance, coordinated action, and robust preparedness. The best answer captures three essential pieces: surveillance that spans humans and animals to detect emerging risks and spillovers early; resilient supply chains so that medicines, vaccines, and essential supplies remain available during climate-related disruptions; and cross-sector collaboration that brings together health, veterinary, agriculture, and environmental sectors to assess risks, share data, and coordinate responses. Together, these elements allow a health system to anticipate and withstand climate-related threats that cross species and ecological boundaries.

Focusing only on clinical care misses the preventive and cross-sector needs of One Health. Considering climate impacts without coordinating across sectors fails to address the interconnected drivers of health risks. Relying solely on technology ignores governance, logistics, and collaboration that are crucial for sustained resilience.
